  1. 1. Validation of An Iteration Free Material Model for Paperboard (NEO)

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Samuel Thomas Staines; [2022]
    Keywords : Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Abstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE

  3. 2. Non-linear Curve Fitting

    University essay from Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Author : Farhad Morad; [2019]
    Keywords : Curve Fitting; Power-exponential function; Gauss-Newton algorithm; Levenberg-Marquardt algorithm; Linear and non-linear curve fitting; Kurvanpassning; Potens-exponential funktion; Gauss-Newton-algoritm; Levenberg-Marquardt-algoritm; Linjär och ickelinjär kurvanpassning;

    Abstract : The work done in this thesis is to examine various methods for curve fitting. Linear least squares and non-linear least squares will be described and compared, and the Newton method, Gauss--Newton method and Levenberg--Marquardt method will be applied to example problems. ..

  4. 3. Path planning for autonomous vehicles using clothoid based smoothing of A* generated paths and optimal control

    University essay from KTH/Numerisk analys, NA

    Author : Marcus Lundberg; [2017]
    Keywords : ;

    Abstract : Autonomous vehicles is a rapidly expanding field and the need for robust and efficient path planners is high. We approach the global path- planning problem for an autonomous load carrier for quarry environments, developed at Volvo Construction Equipment, using two methods: a two- step path planning and path smoothing approach, and a method based on an optimal control formulation of the path planning problem.

  5. 4. 3D imaging using time-correlated single photon counting

    University essay from Signaler och System

    Author : Thomas Neimert-Andersson; [2010]
    Keywords : Laser radar; LADAR; time-of-flight; signal processing; non-linear least squares; esprit; time-correlated single photon counting; three-dimensional imaging; range profiling; deconvolution; wiener filter; richardson-lucy algorithm; image processing; watershed;

    Abstract : This project investigates a laser radar system. The system is based on the principles of time-correlated single photon counting, and by measuring the times-of-flight of reflected photons it can find range profiles and perform three-dimensional imaging of scenes. READ MORE
